Which two conditions do most seeds need in order to germinate?
A. Adequate sunlight
B. Enriched soil
C. Adequate water
D. Warm temperatures
Answer:
I believe it is a and c because plants need sunlight and water
Explanation:
The correct answer of the question about seed germination is that Adequate water and Enriched Soil are the two most important condition in order to germinate seed.
What do you mean seed germination?The fundamental process by which many plant species develop from a single seed into a plant is known as seed germination. This method has an impact on crop output and quality.The growth of a seedling from an angiosperm or gymnosperm seed is a frequent example of seed germination.Rapid water uptake by the seeds during the early stages of germination causes swelling and optimal temperature induced softening of the seed coat. Imbibition is the name given to this phase. Enzymes are activated to begin the growth process. The seed starts to create proteins, respire, and metabolise the food that has been stored after activating its internal physiology. This is the lag phase of seed germination.The seed coat bursts, allowing the radicle to emerge and develop into a main root. The seed begins to take up water from underground. After the radicle and plumule have emerged, the shoot begins to ascend.The seed cell lengthens, divides, and becomes metabolically active in the last stage of seed germination to produce the seedling.
Thus, we can conclude that after analysing and understanding the above given theory the best two realistic conditions in order to germinate good quality of seeds can be that Soil should be enriched and Adequate water supply should be there.

which part of cellular respiration provide most of the energy to run
Answer: The electron transport chain.
Explanation:
Cellular respiration is defined as the mechanism by which living organisms converts organic substances from food such as glucose with the use of oxygen into energy-carrying biomolecules (e.g. adenosine triphosphate or ATP). There are different stages of cellular respiration which includes:
--> glycolysis,
--> pyruvate oxidation,
--> the citric acid or Krebs cycle, and
--> oxidative phosphorylation.
The oxidative phosphorylation also referred to as the ELECTRON TRANSPORT CHAIN occurs in the inner membrane of the mitochondria. It transfers electrons donated by the reduced electron carriers NADH and FADH2 (obtained from glycolysis, the citric acid cycle or fatty acid oxidation) through a series of electrons acceptors, to oxygen.
The electron transport chain is said to produces most of the energy which is 34 ATP molecules, as compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle.
Elements of xylem in a vascular bundle are lesser than those of phloem؟
Answer:
No.
Explanation:
No, elements of xylem in a vascular bundle are not lesser than those of phloem because of the division of xylem progenitor cells that increases the xylem concentration in vascular bundle. The vascular cambium forms more xylem tissue than phloem due to more division of the xylem progenitor cells. so in the light of this discussion we can say that xylem is more in concentration than phloem in a vascular bundle.

Sophia discovered two objects in space with the help of her telescope. She noted down the characteristics of the objects in the chart below.
Which of these statements is most likely correct about Object 1 and Object 2 discovered by Sophia?
A. Object 1 is an inner planet and Object 2 is a comet.
B. Object 2 is an inner planet and Object 1 is a comet.
C. Object 1 is an outer planet and Object 2 is an asteroid.
D. Object 2 is an outer planet and Object 1 is an asteroid.
Answer:
C. Object 1 is an outer planet and Object 2 is an asteroid.
Explanation:
While inner planets can have moons, many moons are a more common feature of outer planets (ex. Jupiter has 79 moons, while Mars has 2). Plus, moons don't orbit asteroids or comets since moons are usually larger. This rules out any of the options involving Object 1 being an inner planet, comet, or asteroid. As for object two, both an asteroid or a comet would make sense as they both have irregular shapes. The only answer that has Object 1 as an outer planet is C. Also Object 1 has rings, which shows that it's an outer planet.

What concept does Hubble's Law most concern?
A. energy lost over time across the universe
B. growing distance between galaxies
C. how stars recycle energy and matter
D. how the universe will eventually end
Hubble's Law most concern with growing distance between galaxies. Thus option B is correct.
What is Hubble's Law ?Hubble’s law refers to the observation in physical cosmology where the movement of galaxies from the Earth at a speed that are proportional to their distance.
The velocity of the galaxy which is called as the redshift.
This laws study physical cosmology and is also known as Hubble-Lemaitre law.
After measuring recession velocity one can determine the distance of the galaxy from us by using Hubble’s equation.
Some limitations are; due to intrinsic motion of galaxies, observed velocity gets influenced and Galaxy orbit due to gravitational movements.
Hubble constant is another unit of measurement, which is used for description of the expansion of the universe. It is 160 km/s per million-light-years.
Thus option B is correct.

Choose the items that complete the sentence about the key features of f(x) = 8x. The y-intercept is Choose... , the asymptote is y = Choose... , and the range is y > Choose... .
Answer:
I suppose that the equation is:
f(x) = 8/x
(You wrote 8x, this is a linear function, so it has no asymptotes, then I assume that the actual function was 8/x)
The y-intercept is the value such that f(x) = 0
Notice that there is no value of x such that 8/x = 0 (if the numerator is never zero, then the quotient can't be zero)
So we do not have an y-intercept.
The asymptote:
Here we have four:
if x tends to zero from the negative side, then:
8/x tends to negative infinity.
if x tends to zero from the positive side, then:
8/x tends to positive infinity.
These two asymptotes can be written as:
[tex]\lim_{n \to \_-0} \frac{8}{x} = -\infty\\ \lim_{n \to \_+0} \frac{8}{x} = +\infty[/tex]
We also have two when x tends to plus infinity (and 8/x goes to zero) and when x tends to negative infinity, such that the function tends to zero again, these two can be written as:
[tex]\lim_{n \to \infty} \frac{8}{x} = 0\\ \lim_{n \to -\infty} \frac{8}{x} = 0[/tex]
Finally, the range:
The only value that y never reaches (only on limits) is:
y = 0
Then the range is the set of all real numbers except the zero, or:
R : { x ∈ R / {0} }

A population of large predators in an ecosystem has been trapped and removed from the area. How would this event most likely change the food web in this ecosystem?
As per the given scenario, the number of small predators will decrease and the number of herbivores will increase. The correct option is C.
A reduction in the pressure of large predators on herbivores would follow from their disappearance.
Since there would be less threats to them from predators, the population of herbivores would probably rise.
The effect would be a reduction in the population of tiny predators, which may have previously depended on the huge predators as a food source.
As a result of this adjustment, the ecosystem's small predator population would decline while the population of herbivores would expand.
Thus, the correct option is C.

In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.
Hope this helped!

Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
Answer:
Lower, low pressure
Explanation:
The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.
Hence, the blanks will be filled with the words
Lower, low pressure.
Two plants with an inated seed shape produced 340ospring. Of those 340, six ospring had a constricted pod shape. What are the genotypes of the parents?
Answer:
The genotype of both parents will be heterozygous for the trait, Ii.
Explanation:
Let us assume that the shape of the seeds is controlled by a single diallelic gene.
Dominant allele I expresses the inflated phenotypeRecessive allele i expresses the constricted phenotypeThe dominant phenotype is inflated seeds, expresses by genotype II and Ii. The dominant allele hides the expression of the recessive allele, so if the genotype has at least one dominant allele, the phenotype will be inflated. The recessive phenotype is constricted seeds, expressed by the genotype ii. In this genotype there is no dominant allele, so the recessive allele can be expressed.The individual with constricted seeds must have two recessive alleles i in its genotype ⇒ ii.
One of the i alleles was inherited from one of the parental plants, while the other parental plant provided the other i allele. So both parental plants must carry the recessive allele in their genotype.
We know that both parental plants have inflated seeds, which is the dominant phenotype.
So, if both parental plants have inflated seeds and also carry the recessive allele, then the parentals´ genotype must be heterozygous, Ii.
Both plants exhibit the dominant inflated phenotype but carry a recessive allele which will be provided to some of the descendants. These last individuals will have constricted seeds.

A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles
